R/V Tioga cruise 729.
WHOI biologist Gareth Lawson and colleagues spent two chilly days in late January locating and capturing tiny marine snails called pteropods in the Gulf of Maine. Acoustic instruments helped them to pinpoint the location of these delicate animals that serve as food for larger animals so they could be brought back to the lab for study. At WHOI, Lawson and fellow biologist Amy Maas are investigating how pteropods will be affected by ocean acidification and how they respond to fluctuations of carbon dioxide in the atmosphere and water.
Image Of the Day caption:
Air temperatures in the teens and icy seas were no match for WHOI postdoctoral researcher Mike Lowe (right) and graduate student Alex Bergan during a two-day research cruise on R/V Tioga in late January off the coast of Maine. Lowe and Bergan, both of whom work in the lab of WHOI biologist Gareth Lawson, recovered a CTD rosette containing water samples drawn at various depths. Back in the lab, they will analyze the water' to draw a more complete picture of the winter environment in the Gulf of Maine. Their work is part of a series of studies that looks at seasonal influences of carbon dioxide in New England waters.
